    Default Catasetum questions

    Hello forum members,

    I have a puzzle and am interested in hearing the thoughts of the collective orchid braintrust here.

    Some background......
    I grow in a shadehouse in the Florida Keys where we reside from late Oct. through late May. The rest of the year we are in New Hampshire. My shadehouse has fully automated, misting/watering/fertilizer while we are not there and watched over by neighbors who are also orchid enthusiasts.

    In spring of 2017 I decided to try a few (5) catasetums for the first time. They did great that first summer and when we got there in Oct. there were spent bloom spikes on 2 of the plants which we were disappointed we had missed. When their new growths started in Dec, I re-potted and put them back under the misters and put the fertilizer to them. They grew like crazy and each produced a nice big fat pseudobulb.

    My wife suggested we do an experiment and bring one of them north to see if it would bloom here so we could see it. Sounded reasonable.

    Initially it was fine out on an east facing screen porch but after about a month leaves turned brown 1 by 1 and they fell off. I stopped watering. Bummer......already gone dormant with no flowering.

    Fast forward to about a week ago and......what's that? Is that a new growth starting already or could it be a late producing spike???????

    Our FL friends think they see a spike starting on 1 of the plants down there but they still have all their leaves.

    Any help on what's going on here? Have I got this plant so confused I've totally messed up it's growth cycle?

    First off, new PB growth, not a spike! I would say it is doubtful you will get a spike but you just might.

    I have lost leaves before they normally drop them before and still got a spike on the bulb. I am one who at the end of their growth cycle take them out of their pots remove all of the sphagnum I use for media and will cut the dying roots off the PB, I then put them in a corner of my covered back porch and leave them till I have new growth in the spring with roots at least 3 inches long they get no water or fertilizer during this time. When I repot them I layer thru the potting process with time released fertilizer and hang them in an area that gets lots of morning light thru my 60% shade cloth and water them daily. I find they like lots of light, water and lots of fertilizer, I still fertilize them every week during the growing period.

    In potting them back up before their dormancy was over you might still get some spikes but they will not be that great they need that time in the winter being left alone. From what I see of the one that has lost leaves you probably have messed up its cycle. This is one species that grows and blooms from March/April till late fall. If you are driving back and forth you could take them with you in May, enjoy the growth and blooms during that time you are there and then bring them back down here in October to put them into dormancy.

    Thanks for your insight Jack. I thought it looked like a new pb but my wife was hoping against hope it was a spike.
    Your last comment about their growth cycle is close but not precisely what I've experienced down in the Keys. Ours have started dormancy in late October and will push out new growths by the first of Jan and by the end of Jan the new growths have full leaves and new roots in excess of 1 inch. Once the leaves are off in the fall I take them out of the misters and hang them in an un-misted section that is still under 50% shade but will get only natural rain which from late Nov- early May is typically very sparse in the Keys. I have read that their length of dormancy is driven by the environment. It makes perfect sense that somewhere that typically gets no colder than a very brief 55f will provide a much shorter dormancy period than even mainland FL. I've been repotting them when they reach the point that new leaves are opening and new roots are a min 1' long. Once repotted, it sounds like I do exactly what you do. I interlayer time release in the potting mix, hang them in the misters (they run 10 minutes at first light and every subsequent 8 hours as long as there is daylight) and still feed them but every 10 days until April which is when I go to a weekly feeding all summer up through Labor Day. I don't trim off old roots or bulbs when I repot but I've only had these a year and a half but maybe I should start doing that?
    Your idea about driving them back and forth is exactly what the experiment was. I think a couple of chilly mid-high 50's nights on the porch in NH must have made the plant think we'd moved it to the arctic circle and it was time for a snooze! Will need to devise a way to keep it warm and try again next year I guess.

    Mine do the same, they start with a new PB in January or so in Cooper City, but I have been told by one of the leading experts on this species to wait till the roots are more then an inch, to wait till between 2-3 inches long before starting to water and fertilize, they will be fine till that time. I had one that had 3 inch roots the middle part of February so I potted it up and it bloomed about a month later, which I did not notice till the end of the bloom, did not expect it to bloom so quickly, it has since bloomed another time and has another spike growing. You know the cold weather we had this past winter I left mine outside the whole time so they can take some cold weather. No reason in the future not to cut the old roots off, they are doing no good to the PB anyway, I cut all except about an inch off mine each fall.
